1 UNITED STATES) JACOB scmcx, or SOUND "amen, CONNECTICVITT, ASSIGNOR TMAGAZINE aErEATme RAZOR COMPANY, CORPORATION N JERSEY 301mm FOBusnmeamnmemacnrnns Application filed April 6 ,'1 927. set "No. 1 1,'29o.

This invention relates to an improved hold er for use in blade grindingand honing machines and is of the type used in the machine described inthe application in which I am a joint inventor. with'Dorlias Nadeau,which application was filed May 19, 1926, Serial Number 110,045.

The device is a holder which retains and passes a blade along thegrinding or honing discs and travels in a rigid track since the grindingis with precision. and the holder is astable rigid one. The inventionembodies a holder of a construction that allows a quick insertion andremoval of blades into and from the holder, which is of advantage inquick production machinery which includes a filling mechanism forinserting blades in the holder and a stacking machine which removes theblades endwise from the holders and places them in stacks for use insafety razors.

The invention can be used in other connecvtions but is primarilyconstructed for the holding of narrow blades such as are used in mymagazine razor patented May 18,1926,

The invention is illustrated in the accompanying drawing in which Figure1 is a side view of a holder for receiving: five blades. Figure 2 is anenlarged section of. the holder closed and Figure 3 is a similar Viewshowing the holder open to receive a blade. Figure 4 is a top view of amultiple: holder showing a set of releasing tools for opening the hold-5 er. Figure 5 is a sectional perspective of the holder and Figure '6 ofmodified form. 7

The holdercan be made in single units each holding a blade butinipractice it is usual to 0 have each holder receive a number ofblades. The invention, can be made in single units but I show in thedrawing a holder for five blades the holder having abase 10 on which isa rigid wall 11. Theparts of the holder Elare usually made of steel andare hardened so as to be durable especially in view of their being slidlengthwise in a track of suitable construction. The holder "has a'platesecured to the wall 11 and I show a plate 12 51 securedby a screw 13 andthe plate and wall is a section of aholder ledge, said led cooperate tohold 'a blade 14 betweenthem at their ends, the blade resting ona'shoulder on oneof the elements such as the shoulder 15'on thefwall11'. The plate 12 is cut away at desired points/such as the hollow'pa-rt16- to give enough resiliency to the plateto enable it to spring alittle torelease-or receive the blade 14.

The plate 12 is designed to be sprung outvwardly to load and unload it,usually in a machine for this purpose and I have illustrated a prong orprongs 17 which is adapted to pass through the hole or holes 18 in thewall 11 so that the plate can be sprung outward as shown in Figure 3.

The outer walls of the wall 11 and plate 12 are tapered towardthe toptoallow the grinding or honing from the holder, by again pressing a set ofprongs 17 against the plate 12', this time in an unloading machine.

discs 19 to bearranged 1 at the proper angle to'treat the edge of theblade 14.

in the quantity In Figure '6 I show a modifiedform of I plate, whichplate 20 is pivoted as at 21 to the wall 11 and the spring 22 holds itin clamping position. The prong 17 in this case engages the plate 20below the pivot to open the holder toinsert or remove a blade 14.

,I claim: i

1. A blade holder for sharpening machines 5 comprising an elongatedrigid back plate, clamping jaws rigidly fixed blades, one of said gebeing of sufficient width to maintain the aws in spaced. relation, saidspace being less than the normal thickness,

to said back plate 1 and of sufficient length to hold a plurality ofjaws having an inner of the blades held, thus enabling the jaws toproperly grip and hold the blades; one of sald clamping jaws being'rigid and the other resilient, said rigid jaw extending uninterruptedlythe whole length of the holder, the said resilient jaw being divided toafford a plurality of clamping lingers adapted to engage the bladesindividually, thus adapting the holder to grip blades of slightly vary-'ing thickness properly.

2. A blade holder for sharpening machines comprising an elongated rigidback plate, and clamping jaws rigidly fixed to said back plate and ofsuflicient length orex- 1 tent to hold a plurality of blades, one ofsaid jaws having a ledge of less width than the thickness of the bladesto be sharpened, so that the normal space between the outer grippinedges of said jaws will be less than the thic ness of the blades to beinserted in the holder, thus enabling the jaws to properly grip and holdthe blades, said back plate being provided with a groove or channel inwhich the backs of the clamping aws fit.

In testimony whereof I aflix m signature.

JACOB CHICK.
